Armstrong Metal Ceilings
Really good company and a lot of practical is involved too. They cover a lot more topics than what we are usually used to and seems to be quicker but they do it in a way that it all sinks in. I would rate it a 10/10 and would recommend using them in the future. I’ve learned a lot more new things than I have in past few years and in some areas I already knew about I feel I know more.
